Abstract
A detailed comparison between the experimental evolution of a two-dimensional soap froth and a next-nearest-neighbour Q = ∞ Potts model on a square lattice starting from identical initial conditions is presented. We compare the pattern evolution, dynamics, distribution functions and correlations of the two systems. We also examine in detail the relation between number or sides and area (Lewis' law) and two measures of pattern disorder. Overall agreement is found between the model and simulation, with a few systematic deviations which suggest that side redistribution is affected by subtle anisotropy and equilibration effects.
